jane pushed a box with 15 N force (an action) what force does the box have on Jane? which law is this?
Answers
Answer:
This is Newton’s third law (forces due to friction). There would be 15N being pushed back at Jane.
Explanation:
Newton’s third law states that for every action there is an equal and opposite reaction. So if Jane pushed with a force of 15N, 15N would be pushed back at her. Hope this helps! :)

How to do this question plz answer
Answers
Explanation:
(i)An analog signal has some feature that is a continuous function of the program material being transmitted. It may take on any of a range of values.
In radio, amplitude, frequency, or phase are features of the radio signal commonly modulated when transmitting an analog signal.
__
(ii)A digital signal has some feature that is a discrete function of the program material being transmitted. It may take on any of a specific set of values.
A digital radio signal typically uses some combination of amplitude, frequency, and phase to represent a discrete state being transmitted. Only specific values of these are used by the transmitter.
(The receiver generally has to deal with corruption of the signal by the transmission channel, so the received set of values may not correlate well with those intended at the transmitter. This is why error-correcting codes are often used with digital signal transmission.)
_____
Additional comment
Analog radio signals are generally transmitted using a carrier wave at a specific frequency (or in some specific frequency range, in the case of frequency modulation). Processing techniques may be used at the transmitter to limit the bandwidth used in the transmission. One commonly-used technique is to limit the transmitted spectrum to one side of the carrier wave frequency. (This is called "single side-band" radio.)
Digital signals offer the opportunity to transmit different bits of the information at different frequencies. Sometimes, "frequency hopping" is used, so that the transmitted carrier wave jumps around from one frequency to another in a predetermined pattern. The effect of this is to spread out the spectrum of the transmitted signal so that average power in any frequency band is significantly reduced. In fact, it may be indistinguishable from background noise, except by a receiver that tunes to the carrier wave in the predetermined frequency pattern.
what observations about disks of dusty material around young stars suggest that planets may be forming in such disks?
Answers
Planets may be forming from dust disks because these disks are filled with completely empty lanes.
We can arrive at this answer because:
The existence of empty lanes allows the dust disks to transform into many different materials, including new planets.In this case, there is a cooling of the dust disk, which cools more and more over time.This cooling causes all the particles in that disk to clot.Coagulation increases the density of the particles and if they are dense enough they can form escape accretions.Escape accretions allow for the formation of planetary embryos, which may form planets in the future.

. Sunita is taking a train to Madurai. Her train has stopped at Trichinapally. She is facing the direction the train will be moving in . She can see a train next to her. The train is also going to Madurai and it leaves first. As the other train leaves, it seems to Sunita as if
Answers
The relative motion of the train next to her is the motion of the other train in her rest frame.
As the other train leaves, it seems to Sunita as if her train is moving backwards
Reason:
The motion of the train Sunita is taking is given by the rate of movement of
objects outside the train from the front side of the train towards the back
side of the train, that way she can tell that the train is moving.
The motion of the other train from the rear side of the train from the rear
side of the train to the front side is a reverse motion to what Sunita
observes when the train is moving forward. Therefore, as the other train
leaves, it seems to Sunita as if her train is moving backwards.

Two motorcycles travel along a straight road heading due north. At t = 0 motorcycle 1 is at x = 50 m and moves with a constant speed of 6.50 m/s; motorcycle 2 starts from rest at x = 0 and moves with constant acceleration. Motorcycle 2 passes motorcycle 1 at the time t = 10.08.
Part B What is the position of the two motorcycles when motorcycle 2 passes motorcycle 1? Express your answer to three significant figures and include the appropriate units.
Part C What is the acceleration of motorcycle 2? Express your answer to three significant figures and include the appropriate units.
Answers
Answer:
Vf = 23 m/s
Explanation:
First we need to find the distance covered by the motorcycle 2 when it passes motorcycle 1. Using the uniform speed equation for motorcycle 1:
s₁ = v₁t₁
where,
s₁ = distance covered by motorcycle 1 = ?
v₁ = speed of motorcycle 1 = 6.5 m/s
t₁ = time = 10 s
Therefore,
s₁ = (6.5 m/s)(10 s)
s₁ = 65 m
Now, for the distance covered by motorcycle 2 at the meeting point. Since, the motorcycle started 50 m ahead of motorcycle 2. Therefore,
s₂ = s₁ + 50 m
s₂ = 65 m + 50 m
s₂ = 115 m
Now, using second equation of motion for motorcycle 2:
s₂ = Vi t + (1/2)at²
where,
Vi = initial velocity of motorcycle 2 = 0 m/s
Therefore,
115 m = (0 m/s)(10 s) + (1/2)(a)(10 s)²
a = 230 m/100 s²
a = 2.3 m/s²
Now, using 1st equation of motion:
Vf = Vi + at
Vf = 0 m/s + (2.3 m/s²)(10 s)
Vf = 23 m/s

a physics student throws a stone horizontally off a cliff. one second later, he throws a second identical stone in exactly the same way. which of the following statements is true?
Answers
The second stone hits the ground exactly one second after the first.
The distance traveled by each stone down the cliff is calculated using second kinematic equation;
[tex]h = v_0_yt + \frac{1}{2} gt^2[/tex]
where;
t is the time of motion [tex]v_0_y[/tex] is the initial vertical velocity of the stone = 0[tex]h = \frac{1}{2} gt^2[/tex]
The time taken by the first stone to hit the ground is calculated as;
[tex]t_1 = \sqrt{\frac{2h}{g} }[/tex]
When compared to the first stone, the time taken by the second stone to hit the ground after 1 second it was released is calculated as
[tex]t_2 = \sqrt{\frac{2h}{g} } + 1[/tex]
[tex]t_2 = t_1 + 1[/tex]
Thus, we can conclude that the second stone hits the ground exactly one second after the first.
"Your question is not complete, it seems be missing the following information;"
A. The second stone hits the ground exactly one second after the first.
B. The second stone hits the ground less than one second after the first
C. The second stone hits the ground more than one second after the first.
D. The second stone hits the ground at the same time as the first.

What is cardio?Any form of exercise that raises your heart rate and keeps it there for a long time is considered cardio. As you start to breathe more quickly and deeply, your respiratory system will start to work harder.
The four components of a fitness program are flexibility, cardio, strength, and power.
The physical exercise that increases muscular strength and fitness is referred to as strength.The capacity to produce the most muscle contractions possible during a movement is referred to as power.Cardio refers to the capacity to handle various circumstances of various lengths.Flexibility is the characteristic that is linked to the range of motion offered by a particular joint.Therefore, the correct option is D.
